SAFETYrGARATI NG.

SPECIFICATION forming part of Letters Patent No. 655,492, dated August7, 1900.

Application iiled April 12, 1900. Serial No. 12,565. (No model.)

T0 @ZZ whom it may concern:

Beit known that I, HERBERT W. KINGS- BURY, (Whose post-office address is7 7 West Third street, Vinona, Minnesota) a citizen of the UnitedStates, residing at Winona, in the county of Winona and State ofMinnesota, have invented certain new and useful Improvements inSafety-Gratings; and I do declare the following to be a full, clear, andeX- act description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebein g had to the accompanying drawings, and to the letters ofreferencen marked thereon, which form a part of this specification.

This invention relates to an improved safety-grating for windows, andhas for its object the provision of a simply and durably constructedappliance of this character which is adapted to be positioned -to iillthe windowopening when the sash is raised, the grating when sopositioned being securely held against displacement, whereby forcibleentrance is effectually discouraged.

The invention consists of the construction and arrangement `of parts setforth in detail in the following description and shown in theaccompanying drawings, in which- Figure l is a View in elevation of awindow with my improved safety-grating in position. Fig. 2 is anenlarged view in perspective of the safety-grating, dotted lines showingthe sections partially folded.

Referring to the drawings by letter, A denotes my improvedsafety-grating, which is in practice adapted to fill the window-openingat the top or bottom dependent on which sash is moved. The grating iscomposed of two sections, each of which is comprised of a number ofhorizontal bars a ce and vertical bars b b, the bars ct being formedfrom fiat strip metal or other suitable material and the bars b beingmade from rod metal or other suitable material. The bars a arepreferably apertured to receive the bars b, and any suitable method ormeans may be employed to The ends of one of the bars b are broughtbeyond the upper and lower bars ct ct to provide pins b b2, the purposeof which will be presently explained.

The sections of the grating are hinged together centrally, a pintle-rodc being passed through the lapped ends of the bars a a, said ends beingpreferably halved, as shown. The rod is rigidly secured to the bars a ofone section, but is passed loosely through apertures in the bars a ofthe other section. The ends of the rod c project beyond the top andbottom bars ct a, providing pins c' c2. At the -outer side of eachsection is a vertical bar d,

which is recessed or apertured to receive the ends of the bars a, andsaid bar CZ is of such width as-Will insure its iitting snugly in thewindowframe, thereby preventing lateral play.

In practice, supposing the grating is to fill the space below the lowersash, said sash is raised to a height in excess of the height of thegrating, and the grating being first partly folded is introduced intothe space, with the bars Zagainst the frame. The grating is then bent,and as it straightens or unfolds it is wedged in the space, after whichthe Window is lowered. The window-frame is provided with sockets whichreceive the lower gratingpins Z22 c2, and in the under side of the sashare sockets which receive the upper pins b c'. With the sash lowered onthe grating no movement of the latter is possible, in viewof thepositive engagement of the pins and sockets, and by the use of the pinsb. b2 to supplement the pins c c2 entrance by removing the frame-beadingand by swinging the grating ends outwardly or inwardly is prevented. Thesashes are locked or secured together by any suitable fasteneraccessible from the inside, so that movement of either sash from theoutside is rendered impossible.

' When secured in position, the grating effectually prevents forcibleentrance and affords the best protection against burglars= and inaddition the grating forms all of the functions of-a lifeguard. Thegrating is quickly removed by elevating the sash, raising the grating,and folding it sufficiently to bring its side out of engagement with theframe. The grating is to be made of different sizes to fit dierentwidths of windows. If it be found that a grating is slightly Awider thanthe window, one of the bars d can be readily removed and the barsa'shortened, after which the bar d is replaced.

The grating although very-efficient in pracloc ing two sections eachconsisting of bars se- I5 cured crosswise of each other, said sectionsbeing foldably secured together centrally on a pintle-rod the ends ofWhich are extended beyond the grating to form pins for engagement withsockets in the sash and frame, and zo other pins on the grating forengagement with other sash and frame sockets.

In testimony whereof:l I affix my signature in presence of twoWitnesses.
